Thank you very much for the video.
I have managed to reproduce the problem and on first look it seems that when you scroll with your finger and leave the application (go to the address bar) the touchend event of the scroller is not fired, which causes the persistent scroller. When you tap again the touchend event is fired correctly.
I will forward this to our development team for further investigation, and I will send you an email as soon as I have more information about it.
Thank you very much for your patience.
